Hi,
Please post a clear picture of the wiring and describe how you load the firmware.

ok, when i load the firmware this is the error.

I connect arduino Leonardo, open arduino builder versión 0.9.1. Load the firmware 5.8 EMUG29PS4 atmega32u4 and push COMX (i tried in different port USB COM4, COM5, COM6 and i have the same results). And then appears the error. And i tried also push button reset of board Leonardo when i push COM4.
